Outcome Measures

Outcome	Result	p-value
PRIMARY Blood Pressure Reduction: Change in Systolic and Diastolic Ambulatory Blood Pressure (mmHg) After 30 Sessions of Intervention	-1; 0; 0; 1	—
SECONDARY Arterial Stiffness: Change in Carotid-femoral Pulse Wave Velocity (m/s) From Pre (Baseline) to Post (After 30 Sessions of Intervention)	-0.0; -0.1	—

Summary

This is a clinical trial to determine whether 30 sessions of heat therapy in the form of hot water immersion is better than 30 sessions of traditional aerobic exercise training on blood pressure reduction in people with elevated or Stage 1 hypertension.
